Per the Daily Mail, Vilanova was diagnosed with cancer in November 2011 while serving as a Barca assistant. Vilanova then ascended to the managerial position in 2012 after the departure of Pep Guardiola.

Vilanova led Barcelona to a dominant showing in the 2012-13 season as they won the La Liga title in impressive fashion. Unfortunately, Vilanova was forced to resign as Barca's manager when his condition worsened in July 2013.

Jose Mourinho expressed his condolences, per Chelsea's official Twitter feed:

In addition to his time as Barcelona's manager, Vilanova managed Palafrugell from 2003 through 2004, and he enjoyed a strong playing career before that.

Vilanova made 52 appearances for the Barcelona B team before going on to play for a number of other clubs, including Figueres and Elche.

Although there has been plenty of focus on Barcelona's somewhat disappointing form in league play this season, as they trail Atletico Madrid by four points for the La Liga lead, that doesn't seem important at this point.

Vilanova was beloved by Barca players and fans, and he will always be remembered for the manner in which he was able to manage a star-laden team and keep egos in check.

Barcelona will finish their season with heavy hearts, but one can only assume that the players will be inspired to perform to the best of their abilities in memory of Vilanova.

He was a fantastic representative of the club, and he will certainly be honored for many years to come.
